I've been cutting dry lately, cuz I'm too lazy to clean oil off. The holesaws still last a looong time.
I'm telling you, a quick spray of mineral spirits and it's cleaner than when you started.
I believe you....do mineral spirits come in a spray can/bottle?
You can get it at any paint supply store. Comes in a quart bottle most of the time. I just put it into a generic hand sprayer.
